Ooshiba and his squad members headed to the administrative building to fight with Nutcracker. His left leg was impaled by Nutcracker's detached kagune, when he jumped towards her to attack her. Then his testicles were crushed by Nutcracker, resulting in his death from shock.
- Ooshiba was modeled after one of the 20 winners among the applicants to the ghoul investigator recruitment campaign. He is associated with "joke" (冗談) in the operation reports attached to the chapters.
